2.1.2 Operation manual

A manual is to be prepared, containing information regarding operation modes, operating instructions for normal and degraded operating modes, operational limitations, user interface description, transfer of control, redundancy, failure detection and identification facilities (automatic, manual), data security, access restrictions, special areas requiring user attention, procedures for start-up, restoration of functions, close-down (e.g. retrieval, parking, etc.). A few guidelines are provided below:

(a) The operational limitations, such as maximum number of persons on gangway (Live Load , LL), the actual distribution of the LL along the gangway, operational length range, wind speed, maximum luffing angle range, vessel accelerations, etc.

(b) Normal use of the gangway with information of:

(i) deployment/retrieval procedures

(ii) operational procedure (preparations prior to personnel transfers, control of flow of people, etc.).

(c) Emergency procedures with information of:

(i) fixed procedures as to when the gangway connection is to be interrupted and when it can be re-established (hazard identification).

(d) Differentiation/definition of controlled vs auto-lift situations.

(e) Continuous maintenance and repair routines to ensure that the gangway and all the appurtenant systems function properly at all times.

2.2.2 Certification procedure

(a) General

The following activities are covered by the Guidelines:

(i) design examination

(ii) survey during fabrication and installation (iii) witness testing and marking.

(b) Type approval (Design and Manufacturing assessment)

Load-carrying and other important components of a gangway are subject to design assessment with respect to strength and suitability for its purpose. A type approval is granted when the design and manufacturing assessment have been concluded without detection of non-compliance towards the Guidelines.

The type approval means that the design as approved can be applied for identical units to be fabricated, i.e.

requested documents need not be submitted for each unit.

The type approval is based on certain conditions and its period of validity may be limited.

CHAPTER 2 DOCUMENTATION AND CERTIFICATION 2.2 Certification

Reference is made to CR Guidelines for Survey of Products for Marine Use, Chapter 3 Type Approval.

(c) Survey during fabrication and installation

Normally, a survey during manufacture of each separate gangway is to be carried out by the Surveyor of the Society in order to ascertain compliance with the approved drawings, other requirements of the Guidelines as well as general good workmanship.

As an alternative to survey during manufacture of each separate gangway, modified survey procedures and survey arrangements may be accepted provided the manufacturer operates a quality-assurance system approved and certified by the Society. Refer to CR Guidelines for Survey of Products for Marine Use, 1.8 Alternative Certification Scheme (ACS).

Before being put into service for the first time, the gangway shall be tested according to the approved

“Testing Procedure for quay and sea trial” by a competent person accepted by flag/state authorities.

(d) Testing and marking

Testing and marking is to be performed as per Chapter 7 requirements of the Guidelines.

(e) Extension of scope of work

Upon request from the customer, the scope of work may be extended beyond the subjects and aspects covered in the Guidelines. Extensions are to be agreed in writing. The Society may, if found necessary, require that the customer presents reference documents for the extended scope of work, such as authority regulations, norms and standards.

In case of disputes regarding interpretations of requirements on which extended work is based, the customer is to contact the publisher/owner of the requirements and obtain their written interpretation. If the publisher/owner is not willing to interpret the disputed requirement, or an interpretation for other reasons cannot be acquired, the Society interpretation will prevail.

(f) Reduction of scope of work

Upon request from and agreed with the customer, parts of the scope of work, components, systems or specific aspects or requirements may be excluded from the scope of work specified in the Guidelines. This will be annotated in the documentary evidence of the completed assignment (certificate).

The Society will not agree to limit the scope of work or parts of the suggested services if they are of the opinion that this may lead to hazards or unacceptable lowering of the safety standar d.

2.2.3 Certificate

(a) As a minimum the certificate is to contain

(i) reference to a signed “factory acceptance tests” report

(ii) design parameters/limitations given in the approval letter or product type approval certificate (PTAC) (iii) list of certified sub-components (see para. 2.2.1/Table 2-2, as applicable)

(iv) reference to valid product type approval certificates/approval letters for the certified sub-components (v) list of tests to be carried out after installation onboard (reference to the approved “testing procedure

for quay and sea trial”).

Note:

The product certificate is issued based on the Approved "Testing Procedure for quay and sea trial" (ref.

para. 2.2.1/Table 2-1).

(b) The Marine Product Certificate will issued by the Surveyor upon completion of the project.
