C7a Mooring Layouts_2020
Mooring analysis involves designing an offshore mooring system to withstand extreme environmental conditions like 100-year storms. Key factors in the mooring layout include the strength of each mooring line, seabed topography, and directions of wind, waves and currents. Common mooring patterns are distributed to balance loads and provide redundancy. Analysis calculates line tensions and vessel excursions in storms, traditionally analyzing mooring and risers separately but now integrated. The purpose is to ensure the vessel stays within acceptable distance limits under worst loads.
Propeller and Rudder

Survey guidelines for oil tankers in service
Survey guidelines for oil tankers in service
Oil Tanker is attributed to the high-risk vessel for the flammability and explosibility features of the
cargoes carrying on it. Once the oil spill occurs on an Oil Tanker, the ocean circumstance will encounter a
serious pollution, especially as the oil tankers have become larger and larger, the oil spill after damage of
oil tanker might lead to a great hazard to the ocean and the adjacent coastlands.
Vessel General Permit
The Vessel General Permit (VGP) authorizes discharges incidental to the normal operation of non-military and non-recreational vessels greater than or equal to 79 feet in length on a nationwide basis. The VGP requires vessel operators to utilize best practices to protect the marine environment. The Coast Guard shares this goal of environmental stewardship and assists the EPA in ensuring vessel compliance with the VGP through inspections and reporting deficiencies. The proposed Small Vessel General Permit would apply similar requirements to non-recreational, non-military vessels less than 79 feet long.
FPSO Requirements
1) Det Norske Veritas (DNV) is a classification society established in 1864 that identifies, assesses, and manages risk, particularly for maritime industries.
2) DNV has a large global presence with over 9,000 employees in 300 offices across 100 countries.
3) DNV has the largest market share for classification of floating production storage and offloading (FPSO) vessels at 40%, focusing on risk assessment and certification of new FPSO builds and conversions.
Modelling and Stress Analysis of the Pig Loop Module of a Piping System.
The failure of any piping system depends on the stress analysis that was performed during the engineering design of the piping system. In designing the pig loop of a submarine manifold to be used in area Y of Niger delta in Nigeria, a proper analysis of the load to which the system could be subjected was carried out using a stress analysis software - ''Triflex piping solutions.'' We employed ASME B31.8 piping code. Various stress values and deflections were analysed at each node to ensure that the design will be on a safe operating condition. Stress utilization was checked for hoop and longitudinal stresses for various scenarios and the worst case scenario was determined. The maximum stress utilization for the worst case scenario was found to be within the limit and thereby meeting with the safety requirement.
