Dynamic Positioning System Service Providers

Dynamic positioning (DP) keeps a vessel in a fixed position or on a precise track using thrusters and reference systems, without anchors. Offshore supply boats, drill ships, cable layers, shuttle tankers, and cruise vessels all depend on DP for safe operations near platforms, subsea infrastructure, and other ships.

A DP fault during operations can mean lost position, collision, or shutdown of critical work. IMO and IMCA rules require regular FMEA testing, annual trials, and class society attendance.

RecordsMarine maintains a directory of dynamic positioning system service providers for DP operators, vessel managers, and offshore contractors, keeping their systems within class.

What DP Servicing Covers

A typical DP service scope includes several streams:

• Annual DP trials and class survey support
• FMEA (Failure Mode and Effects Analysis) updates
• Software upgrades on DP controllers and consoles
• Thruster feedback testing and calibration
• Gyrocompass, MRU, and wind sensor checks
• DGPS, HiPAP, Fanbeam, and CyScan reference system tuning
• Joystick and lever testing on bridge consoles
• Class III redundancy verification
• Operator station and alarm logic checks
• Cyber security audits under IMO MSC.428

Each task generates documentation that class surveyors and charterers review. Companies that service dynamic positioning systems bring DP-trained engineers, calibration tools, and test rigs that simulate fault conditions during trials.

When DP Service Is Needed

Common reasons DP work is booked:

• Annual DP trials required by class and flag state
• Post-modification testing after new sensors or thrusters
• Fault investigation after a DP incident
• Software upgrades from the OEM
• Pre-charter inspection by an oil major or contractor
• DP capability plot verification
• DP1 to DP2 or DP3 class notation upgrade
• Newbuild commissioning trials

Trials usually run during a port call or a quiet operational window. Major upgrades and FMEA updates often need dry dock or extended alongside time.

How to Choose a DP Service Firm

Useful points to check before booking:

• DP-recognized class society approval (DNV, ABS, Lloyd's Register, BV)
• OEM authorization from Kongsberg, Wärtsilä (NACOS), Marine Technologies, or GE
• IMCA-accredited DP engineers on staff
• FMEA writing experience for your DP class
• Mobilization within 48 to 72 hours in major offshore hubs
• Reporting that matches IMO MSC.645 and IMCA M103 formats
• Cyber security testing capability for connected DP systems
• Warranty terms that hold after class sign-off

A clear scope of work, agreed in writing, prevents disputes when class surveyors raise findings during trials.

Industry Standards

DP servicing falls under IMO MSC.645 on DP guidelines, IMCA M103 on DP system requirements, IMCA M117 on DP operator training, IACS UR E22 on cyber resilience, and class society rules for DP1, DP2, and DP3 notations. Oil majors also publish their own DP audit protocols, such as OCIMF OVID and IMCA CMID, which apply to vessels chartered for offshore work.

Frequently Asked Questions

How often are DP trials required?

Annually for all classed DP vessels, with five-yearly FMEA reviews.

What is a DP capability plot?

A graphical record showing how much wind, wave, and current the vessel can hold in DP mode. Required for charter pre-qualification.

Can DP work be done remotely?

Software diagnostics and some sensor checks can. Full trials and FMEA work need engineers onboard.

Who attends DP trials?

A DP-recognized class surveyor plus the attending DP service engineer. Charterer's representatives often join for offshore vessels.

Is DP equipment cyber-rated?

Modern systems must meet IACS UR E22 cyber requirements. Older DP installations often need a cyber upgrade before recertification.
