Project Introduction

Capstone design project of a hydrographic

research ship capable of integrated research

mainly in the arctic areas from shallow coastal bays

and estuaries out to continental shelf and open

ocean waters of the northern region of the world.

2

Missions of the Vessel

Hydrographic surveying and chartings of the arctic

sea bed with the assistance of autonomous

underwater vehicle (AUVs)

Seismic surveying of the seabed and the underlying

geology

Researchers training capabilities

3

Concept of Operations

The vessel shall be designed to perform a complete hydrographic study or the northern arctic passage in the Canadian region.

The vessel’s home port would be in St. John, New Brunswick, Canada

t_Passage,_the_Northern_Sea_Route_and_Northwest_Passage,_and_bathymetry.png

Concept of Operations (contd.)

The main hydrographic mission of the vessel will only allow for the vessel to operate in the most arctic regions through a yearly window based on an arctic zone designated system, and artic class vessel type.

5

Concept of Operations (contd.)

Usage of drones (AUVs)

and sensors onboard

will increase the

coverage areas the

vessel and maximize

window of operations

Ship Electrical System Considerations (contd.)68

ABB DC Link Plant was chosen for RV ANARIS because the plant presents higher efficiencies and advantages over its counterpart, the integrated electric plant (IEP) based on the following criteria:

High fuel efficiency

High system redundancy and operational flexibility

Low maintenance and operating costs

Improved machinery arrangement and weight requirements

AUVs

For RV ANARIS, the HUGIN 3000 AUVs were chosen. Some features of the AUVs include:

Capability to survey up to 3000 m of depth.

Capability for detailed seabed mapping.

A semi fuel cell battery providing more than 60 hours endurance at four knots speed.

A standard HUGIN payload suite includes:

Multi-beam echo sounder

Side scan or synthetic aperture sonar

Sub-bottom profiler

Conductivity temperature density (CTD) etc

75

http://www.safe.no/index.cfm?id=264816

AUVs (contd.)

http://www.arkeotekno.com/

76

Launching phase:

During launch, the hydraulically operated

stinger with the HUGIN AUV is tilted down

into the water and the vehicle is released

by a disconnect mechanism while the ship

is heading against the wind with a speed

of 2-3 knots.

AUVs (contd.)

Recovery phase:

During recovery, the ship is

positioned 50 - 100 meters from

where the AUV surfaces. The

vehicle drop nose with the

recovery line is hooked and

connected to the L/R system

winch. The vehicle is then pulled

onto the stinger and the stinger is

lifted and retracted. During

recovery the ship moves forward

at 1 to 2 knots.

Conclusions81

http://toeflspeakingteacher.com/master-conclusion-sentences/

What’s Next?

Although most aspects of the conceptual design of RV ANARIS was touched, there are still some areas that need refinements and attentions:

VCG,TCG,LCG estimates based on completed GAs

Refine weight estimates after the structural calculations are completed

Seakeeping analysis

Update stability after weights and CGs are refined

CFD analysis of the hull

FEM analysis of the hull

Propeller performance refinement based on an appropriate Kt-Kq graph
