Pointe du Bois Manitoba Deployment Procedure

October 1, 2011 1 Introduction

This document outlines the procedures to be used during the deployment of the Hydro-Kinetic turbine upstream of Manitoba Hydro’s Pointe du Bois Generating Station in south-western Manitoba. Having successfully deployed two smaller turbines, in association with New Energy Corporation, at the same site, with the same test platform, University of Manitoba researchers will deploy a 60kW hydro-kinetic turbine generator using similar methods. Refer to Figure N-1 for a description of identified areas, terms and components. Following that is a graphic showing an aerial photo of the site and some relevant deployment elements.

2 Test Situation 2.1 The test site will be in a small area of the Winnipeg River, designated as

the Forebay for the Point DuBois Generating Station. The specific location is approximately 100m upstream of the Power House, and between piers 2 and 3 of an existing walking bridge.

The attached diagram C20 R4 shows a partial site plan and a general arrangement of the test setup. Drawing C21 R4, also attached, shown a cross section of the deployment and mooring system.

We note that the walkway bridge itself is slated for demolition as part of Manitoba Hydro’s Spillway replacement project, and is not suitable for any support of the test platform – or turbine. It will, however, be used by research personnel to gain access to the test platform after mooring – and also during the actual deployment – to ensure safety of researchers.

2.2 The NORMAL flow of the Winnipeg River is reasonably high in this area –

in the order of 2.5 m/s, which is one of the reasons it was chosen as the

test site. The turbine itself is rated for full output at 3 m/s. However, due to low water levels, the flow may be as little as 1.1 m/s during test.

2.3 In October 2006, an anchoring system was installed into the bottom of the

river bed approximately 100m upstream of the walkway bridge / test site. It consists of two 30mm diameter 2.4m long rods, drilled into the rock, and grouted in place. To each of these a 20m long a 9.5mm (3/8”) steel chain was connected, and at the free end, both were connected to a single 300mm connection ring. This continues to be the basis of the mooring system. See attached Canadian Engineering Design Network paper, July 2007 for details.

2.4 A 30mm (1 ¼”) diameter steel wire rope cable extends the mooring point

downstream, towards the test site. The cable ends approximately 30m upstream of the bridge, and this is the point to which the pontoon boat test structure will be connected using similar wire ropes in a yolk-style two point connection. Refer again to Diagram C20 R4. Deployment of the pontoon boat is covered in the notes.

2.5 The pontoon boat or test platform was used previously by the test group to

test both a 5kW and a 25kW vertical axis kinetic turbine for New Energy Corporation. It is approximately 9.1m long and 5.5m wide (30’ x 18’), supported by two full-length aluminum pontoons.

2.6 A support arm, or A-arm has been constructed of welded web, tubular

steel, and fitted with two hydraulic pistons designed to raise and lower the turbine and support structure (referred to as the “leg”) into the flowing water. The design has taken into account a worst-case scenario – that being the entire leg being full of water.

2.7 The leg itself supports the rotor and houses the generator and speed

increaser (gear box) and is sealed from water ingress. A sump pump (with oil separator) has been installed in the leg to remove any water which may splash in (or minor leaking of seals etc.).

3 Safety 3.1 The system has been designed to allow for the rotor (leg) to be lowered

into the water with the research personnel standing on the walkway bridge, such that no person will be on the test platform during deployment. Once the rotor is fully submerged and proven to be stable, personnel can board the platform using a ladder system and fall arrest equipment. Personnel have received formal fall arrest training.

3.2 Electrical safety is maintained by having break-away cordsets, for both generated power and ancillary (shore) power. A breaker with disconnecting handle has been installed between the generator and the measurement and control box on board the boat – for emergency disconnecting of the power.

3.3 Life jackets will be worn by all deployment personnel during deployment.

Life rings will be onboard both boats, as well as a station at the west end of the foot bridge.

DEPLOYMENT 2012 – UEK Turbine on Pontoon Platform 

 

In early October 2011, the test platform was prepared for a final test at the Manitoba Hydro Point du 

Bois Generating Station. 

A Deployment and Safety manual was prepared and reviewed by the test group.  The manual is attached 

for reference as it includes a list of identities (nomenclature) to ensure consistent terminology for the 

various components.  This list is identified as Figure N‐1.   That document also shows the cables, winches 

and fitting required to safely deploy the pontoon boat with the turbine onboard, and so that will not be 

repeated here. 

Before deployment, the final on‐site fit up included the following work: 

Installation of the Turbine/Generator onto the support arm on the platform 

Connection of cooling pumps for gearbox cooling system 

Connection of bilge pump to oil/water separator system 

Connection of the generator output cables to the termination cabinet at the top of the 

generator support housing 

Installation of the safety disconnect switch on the support arm 

Main output cable from the safety disconnect switch to the data acquisition box at the stern of 

the platform 

Connection of current transformers, voltage transformers and power analyzer to main output 

cable 

Installation of output cable and outlet to on‐shore Power Converter system 

Installation of the acoustic Doppler velocimeter (flow and turbulence measurement) on the 

platform ahead of the turbine 

Installation and connection of pressure transducers around the turbine shroud, and vibration 

sensors to the Data Acquisition device 

Connection of shore power – for the measurement devices and ancillary pumps 

The cable list attached identifies the cables and accessory wiring, with reference to Figure N‐1 for 

equipment descriptions. 

Photo 1 shows the current transformers (one per phase), terminal blocks for phase voltages and a 

voltage transformer, which were used to measure the generator output at the test platform, ahead of 

the main connector (which is shown in Photo 2.  This allowed the generator to be started and test run – 

before connecting the output to the Power Converter on shore.

This is an example of high resolution measurements taken for voltage and current generated by the 12 kW axial flux, permanent magnet generator as driven by a 25 kW vertical axis 4-blade rotor, manufactured by New Energy Corporation. Note time steps of 0.00005 seconds representing a 1/20,000 sampling rate.

A short sample from the start, middle and end of the complete 4R1 sample set demonstrates reasonable voltage stability, with some fluctuation of frequency – as expected with the water velocity varying with time and highly turbulent.
