4 TRANSFER PLANNING
The key to safe operations is the familiarisation and participation of all the involved crew in the
careful planning of the operation.
The Operating Parameters detailed within this document are generic, therefore safe operating
conditions must be determined by onsite supervision with due regard to site specific equipment,
vessels and conditions, taking account of any local conditions and equipment.
Safe transfers require careful planning and supervision.
The following are recommended as a means of ensuring safe transfer operations:
4.1 Risk Assessment and Method Statement
A risk assessment and method statement should be completed by the responsible authority on
board the installation and by the transfer vessel Captain prior to the first transfer operation for the
specific installation and vessel. The risk assessment should be reviewed periodically and the method
statement amended in the event of any substantive changes to equipment, procedures or any other
factors considered relevant.
4.2 Communications
Communications are an important part of controlling transfer operations. Local communication
practice will vary from work group to work group. However, dedicated 3-way radio communication
channels must, as a minimum, be provided between the Crane Operator, vessel Master, and Lift
Supervisor. A suitable radio protocol must be agreed and adhered to. Contingency communications
using a loud speaker or deck tannoy must be available.
Standard hand signals must be used by Crane Banksmen, where required, to supplement the agreed
radio communications.
4.3 Information Exchange
The following transfer vessel information must be provided to the installation:
i. General layout including the landing area position.
ii. Limiting environmental parameters for vessel station keeping.
iii. Onboard marine personnel transfer procedures.
The following installation information must be provided to the transfer vessel:
i. Crane position and hoist speed.
ii. General layout including the landing area position.
iii. Limiting environmental parameters for crane operations.
iv. Onboard marine personnel transfer procedures including responsible persons.
v. Communications channels.
vi. Any relevant information regarding local currents, field operations etc.
