Vessel collision investigation for marine claim

When a ship launched into navigation and shipping, a marine incident at sea such as "Motor vessel collision" was unforeseen. Job of vessel collision investigation must be carried out for marine claim

For the risks at sea are immense dangers and force majeure, so a ship owners always take part in the insurance of their ship's Hull and Cargo insurance.

The insurance policy holders will be compensated for damages / losses after an accident occurring on their ship on property, hull, machinery, equipment, casualties, economic losses, environmental crisis, and cargo carried.


But in order to prove that the cause of the maritime accident is within the responsibility of the insurer, the policy holder requires an independent surveyor of third party inspection is AIM.

When the consequences occur with small value, then the parties will negotiate themselves (negotiating compensation), but occurring with too huge value of losses, the Court will be the place to judge all and end of dispute.

The Insurance Company (Usually P&I) and the Insured Company (usually the shipowner) always make a point of protecting their own interests (usually denying their liability). Therefore, a Joint Survey for a collision of vessel or a marine accident is always important. Only qualified and experienced marine surveyors companies like AIM will have enough expertise and Skill (engineering and technician, technology, science, regulation and rules, acknowledging) to protect for their clients' legitimate rights against other concerned parties.

A vessel collision is the physical impact this occurs either a ship to another vessel or to object resulting in a damaging accident.
