BAB AL MANDEB - 2 VESSELS STRUCK & ON FIRE

Two vessels catch fire in the Bab el-Mandeb Strait, what happens afterward depends on the extent of the damage. Generally, there are several possible outcomes:
》Fire extinguished, vessel remains afloat: If the crew or salvage teams successfully control the fire and the hull remains intact, the vessel may continue floating. It will usually be escorted by tugboats to a safe anchorage or port for inspection and repairs.
》Loss of buoyancy: If the fire weakens the hull or allows seawater to enter through damaged sections, the vessel can begin listing (leaning) and may eventually sink.
》Abandonment and drifting: If the crew evacuates and the fire is not controlled, the vessel may continue burning while drifting with currents and wind. Salvage companies may later attempt to recover it if conditions are safe.
》Environmental and navigational hazards: A burned or partially submerged vessel can leak fuel or cargo, creating pollution and posing a hazard to other ships. Authorities may establish exclusion zones and deploy pollution response teams.

BAB AL MANDED & FUEL PRICE SPIKE

The Bab el-Mandeb Strait is one of the world's most important maritime chokepoints. It connects the Red Sea to the Gulf of Aden and the Indian Ocean, making it a vital route for ships traveling between Europe, Asia, and the Middle East via the Suez Canal.

When this route is disrupted by conflict, attacks on merchant ships, or military tensions, global fuel prices can rise for several reasons:
● Longer shipping routes: Many oil and LNG tankers avoid the Red Sea and instead sail around the Cape of Good Hope in South Africa. This adds about 10–15 days to a voyage, increasing fuel consumption and operating costs.
● Higher insurance costs: Ships passing through high-risk areas face much higher war-risk insurance premiums, which are passed on to buyers.
● Reduced supply efficiency: Oil and gas take longer to reach markets, tightening supply even if production remains unchanged.
● Higher freight rates: Tanker and container shipping costs increase, raising the cost of transporting crude oil, refined fuels, and many other goods.
● Market uncertainty: Traders often bid up oil prices because of concerns that supplies could be disrupted further, adding a risk premium to crude prices.

The impact is especially significant because roughly 10–12% of global seaborne oil trade and a substantial share of LNG shipments normally transit the Red Sea route.

GLOBAL DISRUPTION IN MARITIME, OIL & GAS INDUSTRIES

A direct US-Iran war would have major consequences for the global maritime and oil & gas industries, especially because the Persian Gulf and Strait of Hormuz are among the world's most important energy corridors.

Maritime industry impacts
》The Strait of Hormuz carries roughly 20% of global oil consumption and a significant share of LNG exports, particularly from Qatar.
》Shipping insurance (war-risk premiums) would increase sharply.
》Freight rates for tankers would rise due to higher operating risks.
》Vessel rerouting, naval escorts, and longer transit times would increase costs.
》Ports in the Gulf could face disruptions if military activity intensifies.
》Shipowners may avoid high-risk areas, reducing tanker availability.

Oil & gas industry impacts
● Crude oil prices could rise significantly depending on the duration and severity of the conflict.
● LNG prices would likely increase because Qatar is one of the world's largest LNG exporters.
● Offshore production, subsea infrastructure, pipelines, and export terminals in the Gulf could face operational risks.
● Energy companies may delay investments or temporarily suspend projects in high-risk areas.
● Strategic petroleum reserves could be released by major consuming countries to stabilize markets if supply is disrupted.

Global economic effects
◇ Higher fuel prices would increase transportation and manufacturing costs worldwide.
◇ Inflation could rise as energy costs feed through to goods and services.
◇ Airlines, shipping companies, and energy-intensive industries would face higher operating expenses.
◇ Financial markets would likely become more volatile as investors move toward safer assets.

Potential opportunities While disruptive overall, some sectors may benefit:
☆ Oil & gas service companies could see increased demand for asset integrity, inspection, maintenance, and security services.
☆ Defense and maritime security industries may experience higher spending.
☆ Renewable energy, energy efficiency, and alternative fuels could receive greater investment as countries seek to reduce dependence on vulnerable supply routes.
☆ Companies involved in digital maritime solutions, predictive maintenance, and infrastructure resilience may find new opportunities.

WHAT IF - SEAWATER AS FUEL

Using seawater directly as fuel for a marine vessel is not currently possible because seawater itself does not contain readily usable chemical energy. However, seawater can be used as a source of fuel in several advanced concepts:

1. Hydrogen from Seawater
Seawater contains water (H₂O), which can be split into hydrogen and oxygen through electrolysis.
Process:
● Seawater → Desalination/Purification
● Electrolysis → Hydrogen (H₂) + Oxygen (O₂)
● Hydrogen used in:
Fuel cells
Hydrogen internal combustion engines

Advantages
● Virtually unlimited resource at sea.
● Zero carbon emissions at point of use.

Challenges
● Electrolysis requires significant electricity.
● Producing hydrogen onboard consumes more energy than the hydrogen releases.
● Large storage tanks are needed.

2. Nuclear-Powered Hydrogen Production
◇ Future vessels could use small modular reactors to generate electricity, then produce hydrogen from seawater onboard.

Examples:
◇ Naval submarines and aircraft carriers already use nuclear power, though not for hydrogen production.

3. Seawater + Aluminum Reaction
Some experimental systems use aluminum or other reactive metals:
■ Aluminum + seawater → Hydrogen gas + heat
■ Hydrogen then powers fuel cells.
This is promising for long-endurance unmanned vessels but requires replenishing aluminum.

4. Direct Seawater Fuel Cells (Research Stage)
Scientists are researching fuel cells that use dissolved minerals and ions in seawater to generate electricity directly. Power density remains too low for large commercial ships.

Potential for Malaysia
Given Malaysia's maritime sector and abundant seawater, a practical future pathway could be:

》Offshore renewable energy (solar, wind, wave).
》Produce green hydrogen from seawater.
》Store hydrogen as:
Compressed H₂
Liquid hydrogen
Ammonia (NH₃)
》Use hydrogen/ammonia-powered fishing vessels, tuna longliners, and coastal vessels.

CARGO TANK GAS FREE

The cargo tank degassing process is carried out to remove flammable, toxic, or inert gases from a tank and replace them with fresh air so that the tank becomes safe for inspection, maintenance, repairs, or hot work.

Typical Cargo Tank Degassing Procedure

1. Cargo Discharge Completion
× Ensure all cargo has been discharged.
× Strip cargo lines and pumps.
× Drain remaining residues to slop tanks where applicable.

2. Tank Washing
- Wash cargo tanks using fixed or portable tank cleaning machines.
- Remove cargo residues from tank surfaces.
- Collect wash water in slop tanks.

3. Purging (If Tank Is Inerted)
> Replace inert gas with fresh air, or in some cases use an intermediate gas depending on cargo type.
> Reduce hydrocarbon concentration gradually.

4. Ventilation / Degassing
* Open designated tank openings and vents.
* Use fixed or portable fans/blowers.
* Introduce fresh air and exhaust contaminated atmosphere through venting systems.
* Continue until hydrocarbon levels are below required limits.

5. Atmosphere Testing
Test at:
● Tank top
● Mid-depth
● Tank bottom
● Pump room (if applicable)

Typical acceptance criteria:
Oxygen: approximately 20.9%
● Hydrocarbon concentration: below 1% LFL (or as company procedures require)
● Toxic gases (H₂S, benzene, etc.) below occupational exposure limits.

6. Gas-Free Certification
☆ Authorized officer or marine chemist conducts final testing.
☆ Issue Gas-Free Certificate if required.

7. Entry Permit
Before personnel entry:
■ Complete enclosed-space entry permit.
■ Establish continuous ventilation.
■ Prepare rescue equipment and standby personnel.

Example Sequence for a Crude Oil Tanker
》Discharge crude oil.
》Crude Oil Washing (COW).
》Water wash.
》Strip residues.
》Ventilate tanks using portable fans.
》Measure O₂ and hydrocarbon levels.
》Gas-free certification.
》Tank inspection or repair.

Safety Precautions
◇ No smoking or ignition sources.
◇ Use intrinsically safe equipment.
◇ Monitor atmosphere continuously.
◇ Follow enclosed-space entry procedures.
◇ Maintain communication with personnel inside tanks.

For oil tankers, chemical tankers, and LNG/LPG carriers, the detailed degassing procedure differs because of the cargo characteristics and regulatory requirements.
