which as a word also has the meaning of evaluation and measuring.
Through the effective operation of the complete service system
(i.e. the "METE Plan") composed of the above four items, the ship
management company can keep abreast of the hull structure condition of the
fleet and make timely maintenance plans to ensure the safety of the hull
I. 3D Modeling Based Planned Maintenance Scheme for Hull
With the increasing prominence of ship safety issues and PSC
inspections, the inspection and maintenance of hull structures receive ever
greater attention from various parties. Planned inspection and maintenance of
the ship's hull structure and equipment can provide a comprehensive and
accurate grasp of the ship's structural condition, properly track and deal with
the ship's defects, formulate scientific and reasonable repair plans, reduce
the possibility of unplanned repairs affecting the normal operation of the ship,
fundamentally reducing the risk of the ship's operation process and increasing
the company's confidence in the ship's safety standard and reliability.

II. Goal Oriented Structural Strength Evaluation for Hull
Structural strength is one of the most important aspects of ship
safety, and among the shipwrecks in recent years, apart from human factors and
bad weather, a considerable percentage of shipwrecks were caused by
insufficient structural strength or structural damage to the hull. Therefore,
the structural strength of ships, especially large and old ships, has aroused
the general concern of the shipping industry.
As a shipping company, it is vital to keep track of the
structural strength status of its fleet of ships to maintain the company's safe
Through structural strength assessments, the user can:
Provide professional hull structure
consulting information for shipowners.
Assess the structural condition of ships
based on build dimensions and latest thickness measurements.
Provide a reference for engine/crew when
maintaining, servicing and repairing ships.
Guide the maintenance technicians / ship crew
to inspect the hull structure.
Provide a reference for corrosion control
during ship operations.
Accumulation of technical expertise and
provide a reference for shipowners to develop and select ship types in the
1. An in-depth reading of structural design and features
As part of the assessment, an in-depth reading and analysis of
the structural design of the subject is undertaken to understand the structural
design approach and thereby analyze its strengths and weaknesses;
structural layout and its laws;
material usage – material types and
assessment and analysis of the
characterization of the location of the structure of the assessment area.
Structural interpretation and analysis also provides shipowners
with in-depth structural consulting information, which helps shipowners to have
an in-depth understanding of the characteristics and conditions of the target
vessel and the entire fleet, thus helping to arrange reasonable inspection,
maintenance and operation.
2. Provide reference for use, maintenance and repair of ships
After comprehensive calculations and analysis, it will be
possible to identify potential weaknesses and possible problems within the life
cycle of a particular ship. At the same time, based on the results of the
evaluation of build dimensions and thickness measurements, the original loading
pattern will be improved or limited accordingly to ensure that the total
longitudinal and local strengths meet the service requirements during the ship's
Through calculations and analysis, areas of insufficient
structural strength or high stress levels are identified and recommended to
shipowners and crews for priority attention in their daily
As a professional ship inspection organization, CCS has perfect
calculation software and leading finite element analysis tools in the industry
for the calculation and analysis of the structural strength of ships.
3. According to the characteristics of different ship types, structural
strength assessment and ship type studies mainly include the following
Strength evaluation and analysis of
Calculation and analysis of direct strength
with structural finite element method.
Fatigue strength assessment.
Strength evaluation of real ship structure.
III. Training on Hull Structure Inspection and Maintenance
Due to vessel development trends there is an increase in the
size and number of large ships and a consequent increase in the size of the crew,
the human factor is attracting more and more attention from IMO and shipping
companies who urgently require crew members and engine operators to acquire certain
knowledge of ship structure and maintenance.
Through many years of theoretical research and inspection
practice, CCS has prepared a series of training materials with reference to the
current situation of shipping and the key points of port state inspection, in
order to meet the work demands and fit the characteristics of the crew and
engine services. As part of the teaching coursework in this series, the
training on hull structure inspection, maintenance and repair includes the basic
knowledge of hull structure, the key points of structure inspection and the
handling of defects, etc. The coursework has been compiled to emulate the
actual situation of the engine service and crew, and is easy to understand and
effective in helping crew members master the control standards of hull
structure inspection and repair.
The training on hull structure inspe’sction, maintenance and
repair is conducive to improving the level of inspection, maintenance/servicing
of the vessel by the crew and engine services, thus improving the safety level
of the ship operation.
Training contents include:
Knowledge of hull structure
Basic knowledge of hull structure.
Knowledge of hull structure details and
Ship stability knowledge.

Training is provided mainly in the form of lectures,
supplemented by computer multimedia materials.
IV. CCS Emergency Response Service (CCS-ERS)
Emergency Response Service (ERS) means that, for ships that are
included in the emergency response database, with related information on stability
and structural strength, and the ship owner / manager has signed an ERS agreement
in advance with the classification society, can get emergency response
assistance. In cases where a vessel has suffered a collision at sea, grounding,
oil spill, or other accident, then upon the request for assistance from the manager
or owner, a permanent shore-based emergency response agency, part of the
classification society, will quickly assemble, activate the ship's emergency
response database, provide calculations and analyses including breakage
stability, residual strength, oil spill, etc. as required by the shipowner/ship
management company. The ERS team can also provide round-the-clock technical
support throughout the emergency to assist with the successful assistance to a ship
in danger, and provide advisory services to inform the final decision of the
master/owner/ship management company.
In an emergency situation, the best measures to save the crew,
cargo and actions to protect the environment are not always obvious. Improper
handling of cabin water and oil spills caused by collisions, groundings, fires,
explosions or bad weather can make the situation worse. At sea, crews and their
managers need accurate technical information to mitigate the damaging effects
of an accident as quickly as possible. In such cases, a comprehensive
assessment of the ship's stability and total longitudinal strength is essential.
Exactly for the above-mentioned reasons, CCS-ERS has been established to
provide this technical support 24 hours a day, 7 days a week, 365 days a year.
CCS-ERS functions include:
1. Fracture stability
and floatation analysis;
2. Residual total
longitudinal strength analysis;
3. Stranding stability and total
longitudinal strength analysis;
4. Damage and oil
5. Assessment of the
stability of the integrity of the firefighting decks of passenger ships;
6. Provide emergency
treatment recommendations to maintain minimum stability and safe hull strength.
