The maritime integrity topic applies to all floating installations, including jack-up drilling units. The maritime hazards are:
- loss of stability, arising from collision or uncontrolled flooding
- loss of position, arising from some failure within the mooring system or dynamic positioning (DP) system.
Present topic areas of attention include:
- assurance of the integrity of mooring systems for production installations
- management of offloading operations to shuttle tanker, including inert gas and hydrocarbon blanket gas systems
- suitable inspection and repair programs to ensure continued watertight integrity
- arrangements to ensure the provision of competent, experienced personnel, both offshore and onshore
- supervision and control of DP operations of the installation, and of vessels in close attendance, including gangway management
- control and management of work activities inside ballast and cargo tanks.
Our topic strategy describes our work in this area.
This safety notice highlights the need to ensure suitable and sufficient assessment of the adequacy of venting arrangements for cargo oil tanks on FPSO and FSU installations.
- Floating production storage and offloading (FPSO)
Mooring inspection (Safety Notice 3/2005) For operators of monohull weather vaning FPSO's and FSU's. It explains why they need to ensure that the top sections of their mooring chains are not subject to excessive wear that can affect the integrity of the mooring system.
