Tracing and membrane sheet positioning are done.

9) Installation of membrane sheets

Installation of the membrane sheets and temporary fixing by clamps are

done.

10) Tack welding

Tack welding of the edge of membrane sheets onto the anchoring pieces

and/or on the overlapped membrane sheet already in place are done.

11) Continuous welding operation

Continuous welding operation is achieved in order to ensure tightness of

the primary barrier. This welding operation is performed either manually

or automatically.

Simultaneously, angle pieces are put in place and welded as for the

membrane sheets.

3.4 DOGS (DEO Open Gateway Station)

1. General

To access the DEO-NET information, DOGS is a gateway between the DEO-

NET and the external network. The DOGS provides a network interface for the

external Ether-net.

The protocol for the data transition with external devices is objective linking and

embedding for process control.

1. General

DOPC ІІ is a multi-function controller employing control loops, logic functions,sequence control and I/O processing.

- Built-in control / calculation algorithms

- Sequence control implemented by CL (Control Language)

- Distributed I/O for space saving

- Remote I/O capability by fiber optic connection

- Peer to peer communication with other DOPC ІІs over the DEO-NET

using the tag name basis

- Memory back-up by flash ROM

DOPC ІІ consists of ;

- DOCM (DOPC Control Module)

This is a main module of the DOPC ІІ consisting of the control

modules and the communication interface modules.

- Distributed I/O

The I/O modules are mounted on DIN rail.

2. DOCM (DOPC Control Module)

DOCM Configuration shows the DOCM system. The DOCM is composed of the

following modules.

- Control Module (MSC)

- Ethernet Module (ETM)

- X-BUS Module (XBM)

Three (3) sets of control modules (MSC) have redundant configuration, and

execute the same processing synchronized with each other. The ethernet module(ETM) and the X-BUS module (XBM) compare outputs of three (3) MSCs, and

get data by “logic of majority”, i.e., 2 out of 3. Even though one of MSC outputs

incorrect data, the remaining two (2) data are correct and used for the control and

monitoring.

grouped to extension alarm groups and extension alarm panel annunciate the

group alarm status. One audible buzzer does the alarm annunciation by extensionalarm panels and annunciation lamps corresponded to extension alarm groups.

The extension alarm panel consists of two portions. One is extension alarm.

Another is engineer call portion. Both units combined a unit panel. The signals

Extension alarm indicator consists of the color LCD indicator. A set of LCD can

be displayed both extension alarm indication and duty indication on an extension

alarm panel.

One set of duty selector is furnished in the Cargo Control Console and Main

3.10.2 Engineer’s Alarm and Patrolman System

1. Engineer’s Alarm


67/311


The Engineer’s alarm is a statutory requirement under SOLAS.

The system is arranged to provide audible and visual alarms on the indicator

columns, located around the engine room, in the ECR, in the CCR and on the

extension alarm panels (engineers’ cabin panels and public room panels).

Activation of the Engineer’s alarm may be carried out at push buttons in the ECR

or at any of the Patrolman panels locate in the Engine Room, which are also

fitted with an Engineer’s alarm push button.

In addition, the Engineer’s alarm is activated automatically in the event of any

machinery alarm not being acknowledged within 10 min.

Cancellation of the Engineer’s alarm can be carried out at the ECR only and not

from the local push buttons.

The manual activation of the Engineer’s alarm is not dependent upon the engine

room operation mode, “Manned” or “Unmanned”.

2. Patrolman Alarm

The patrolman system is provided in accordance with the requirements in the

Code on Alarm and Indicators, 1995”

The system is arranged to provided audible and visual alarms on each of the

engineers’ cabin panels and public room panels attached to the extension alarm

system, on the indicator columns located around the engine room and in the ECR.

The system may be started or stopped by push buttons located in the ECR

console, and the main entrances to the Engine Room. In each case, the status will

be indicated by a lamp or cluster LED display located adjacent to each on/off

push button.

When the patrolman is first started, the run signal is indicated IAS graphic. An

indication will remain on the UMS panel of the screen as ling as the patrolman is

still active.

b) The gasket to be placed and the nuts to be screwed on bolts by hand.

c) Tighten the nuts diagonally

i.e. eight (8) bolts flange adopt the following tightening order :

1 – 5 – 7 – 3 – 8 – 4 – 6 – 2

The nuts to be tightened four (4) times as follow by using torque wrench.

(1) 1st tight : 20 % of tightening torque given on page 8 thru 7.

(2) 2nd tight : 50% of tightening torque given on page 8 thru 7.

(3) 3rd tight : 80% of tightening torque given on page 8 thru 7.

(4) 4th tight : 100% of tightening torque given on page 8 thru 7.

4.2.3 Mode Selection

1. Ballast and Laden Mode

There are two pressure controllers, one for Laden Voyage and one for Ballast

Voyage, in the GMS that tell the Burner Management System (BMS) how much

Fig. 1 Ballast and Laden Mode Logic


84/311


boil-off gas is available to the burner or how much gas has to be released toatmosphere to keep the vapour header pressure at its set point.

Manual inputs are the “Estimated BOG Flow” in Laden and Ballast mode and the

pressure selection switch that enables the operator to select between absolute or

gauge pressure (for Laden mode).

The pressure controllers will protect the cargo tanks and adjust the “Available

BOG Flow” according to its set point. To control the vapour header pressure

either the ballast or laden pressure controller will be active at all times.

The logic is the same for ballast and laden mode but separate controllers are used

for the two.

Switching between Laden and Ballast mode is performed during loading /

unloading.
