TASK APPROPRIATE MODE

(TAM)

•HEMP Processes used to

support decision to step down

of Loss of Position

Examples of CAM

•Diving Operations,Working within 500 m zone of surface

facilities and critical sub surface assets

•MODU’s- Non shearables through BOP, in Hydrocarbon

zone

Examples of TAM

•Working outside 500 m zone and in drift off confition

•ROV survey outside 500 m zone

DEMONSTRATING COMPETENCY!

ARTICULATING THE FOLLOWING IS A METHOD OF DEMONSTRATING COMPETENCE.

• The redundancy concept of the DP vessel they are serving on.

• The configuration(s) that the vessel needs to be set up in (CAM and TAM)

and the post failure capability of the vessel corresponding to those

configuration(s).

• The impact caused by non-availability of equipment due to inspection repair

maintenance activities on post failure capability.

• The processes in place to defend the redundancy concept.

• Their role in defending the redundancy concept and preventing the potential

for a loss of position.

DP Loss of Position /Significant Incidents-Granularity


SUMMARY: The Coast Guard proposes to establish minimum design,

operation, training, and manning standards for mobile offshore drilling

units (MODUs) and other vessels using dynamic positioning systems

to engage in Outer Continental Shelf activities. Establishing these

minimum standards is necessary to improve the safety of people and

property involved in such operations and the protection of the

environment in which they operate. This notice of proposed

rulemaking would decrease the risk of a loss of position by a

dynamically-positioned MODU or other vessel that could result in a

fire, explosion, or subsea spill, and supports the Coast Guard’s

strategic goals of maritime safety and protection of natural resources.

USCG NPRM SUMMATION


� THE DYNAMIC POSITIONING COMMITTEE’S MISSION IS

TO

� encourage exchange of information,

� discussion of technology, training and education,

� foster improvement of DP reliability, develop guidelines,

and address any other issues pertinent to dynamic

positioning that facilitate incident free execution of DP

operations, and that are consistent with the objectives of

the Marine Technology Society.

� “develop guidelines, and address any other issues pertinent to dynamic positioning that facilitate incident free execution of DP operations”

MTS DP COMMITTEE- MISSION STATEMENT


USCG NPRM - KEY THEMES

• DPO (Dynamic Positioning Operator) Certification Qualifications,

Competency and Manning Requirements.

• Addressed by MTS DP GUIDANCE DOCUMENTS

• DP Equipped Vessel Operations: Requirement for vessels to operate with

a vessel and industrial mission specific - Activity Specific Operating

Criteria / Well Specific Operating Criteria, including identification of

operations requiring CAM configuration and TAM configuration.

• Addressed by MTS DP GUIDANCE DOCUMENTS

• DPSAO ( DP Systems Assurance Organization).

• MTS DP GUIDANCE DOCUMENTS- Performance Standard

• MTS GAP ANALYSIS TOOLS- Verification and Measure against the

performance standard


INDUSTRY-EARNING THE LICENSE TO OPERATE

Collaboration

• Incident Free DP Operations

• Shared Learnings
