eSubsea estimate the design loads and do project specific design load estimation as part of the subsea engineering, design and verification assignment. This include establishing the basic loads, load and design factors and combining these into load combinations to be used in the structural analysis and design of the structure or object.

Limit State Design

eSubsea perform structural design according to the principles of limit state design method. All identified forms of failure are checked within the respective group of limit states (ultimate limit state ULS, accidental limit state ALS, serviceability limit state SLS, progressive collapse limit state PLS and fatigue limit state FLS). The factor of safety (FoS) is established.

Loads and Load Factors

The design loads and forces including all required factors adding to the total level of safety will be established using the codes, standards and recommendation applicable for subsea structures and offshore use (ASME, DNV, NORSOK, ISO, API, Eurocode etc.)

Design load estimation - eSubsea

eSubsea estimate the following design loads for the design of offshore and subsea structures, parts or components:

Subsea design load estimation is usually the first step on any subsea or offshore engineering task and will hence be included in most assignments and documented in the project design basis.
