iii) Identify areas of the unit which do not comply with the Code. iv) Report on any items which may prevent the MODU annual survey being endorsed.
The unit carries sufficient life saving equipment for 32 people. When you arrive there will be 32 people onboard (32 POB).
a) Detail the preparations you will make in order to conduct such a survey, listing the equipment you would take and, the precautions required for working as a surveyor under these circumstances. (15%).
b) During your survey the Offshore Installation Manager (OIM) advises you that the there are no problems with the unit. You later find that the engineering staff are aware that the fire detection system is not operational. Explain how you would deal with this situation and why the statement of the OIM is now a major concern. (20%).
c) During the survey you find that the freefall lifeboat mounted on the unit is damaged and unusable. The lifeboat capacity of the unit no longer satisfies the requirements of the MODU code and the unit is at sea.
Explain how you would deal with this situation. (15%).
